币界网报道：The Cybernews research team revealed that 16 billion login credentials of online service providers including Apple, Google, and Facebook were leaked, of which the largest number of records in a single database reached 3.5 billion. Researchers found that this data was mainly exposed through unencrypted Elasticsearch or object storage instances, and the leaked data included access tokens, session cookies, and account metadata stolen by information theft malware. This incident poses a serious threat to the cryptocurrency industry: attackers may use leaked credentials to launch targeted account takeovers, especially for platforms that host wallets or associated emails. Some wallets allow mnemonics to be backed up to cloud services, which further amplifies the risk. Security experts recommend that users update passwords immediately, enable two-factor authentication, and avoid storing recovery phrases in non-secure digital environments. The identity of the original holder of the data is not yet clear, but researchers have confirmed that some databases may belong to cybercrime organizations.
